Hi @Arthur Just curious here to know if one can simulate acoustic performance for an auditorium with multiple sound sources (loudspeakers). I would be grateful if you may point me towards the right direction, a tutorial somewhere maybe?
Hi,
Set up a point source as usual. Then select it and open the object properties dialog. Find the pachyderm icon and click it. The drop down at the top has an open for common loudspeaker format. Once you select it, it will open a file dialog so you can go find your clf file.
If you don’t know what a clf file is, see the Pachyderm help menu to get to the website for clf.
Once you select a file and open it, controls sounds be pretty self explanatory. Let me know if you have questions.

Thanks Arthur! I will test that out
Hi @Arthur I have tried using some CLF files from JBL but not succeeded in getting anything to work in Grasshopper. When I use a Geodesic Source everything works well, but the loudspeakers are giving me problems. From the collection of CLF files I have, I was able to import one into the script, but still I only got nulls from the analysis. I have added the reference files, please have a look at them.
Acoustic Sample.zip (2.2 MB)
Got it. I’ll take a look this evening.
Hi,
Sorry about that. This got away from me…
Your problem is that power is zero…
Compare this with power on the omni source:
Obviously, you have to have a non-zero source power level for this to work. No power, everything is zeros - the first time we divide by zero, or take the log of zero, you get nonsense - hence NAN.
So - please try again - use a non-zero source power level. Please let me know if this works for you.
Arthur
